On the critical polynomial of functionals related to p-area (1 < p < 1e) and p-Laplace (1 < p 64 2) type operators

We consider a class of quasilinear elliptic equations whose principal part includes the p-area (for 1 < p < l) and the p-Laplace (for 1 < pa2) operator. For the critical points of the associated functional, we provide estimates of the corresponding critical polynomial
